Blue Tit Update

Yesterday I blogged about 2 ringed Blue Tits that we'd found using 2 of the nestboxes at Linacre Reservoirs. I checked with Dave, our data manager at Sorby Breck Ringing Group, who told me that both birds had been ringed by us last year at Linacre.

The first bird had been ringed by me in March 2014 as a 5 female, which means it was born in 2013. The second bird was even more interesting, as it had been ringed on exactly the same day, but a year earlier i.e. on 17th May 2014, as a pullus in one of the nestboxes at Linacre, by Ray, my ringing trainer. This is the first record of a Linacre-born Blue Tit using one of the boxes to raise its own chicks.
